The first step: Prepare materials, cardboard (old calendar cards), wallpaper knife, ruler, pencil, double-sided tape, and string.

Step 2: Leave 0.5~1.0cm on each side of the cardboard, draw a number of parallel lines into equal parts, and then cut with a wallpaper knife.

Step 3: Roll the cardboard into an arc.

Step 4: Paste them together, cut the scraps into thin strips to make tassels, then attach the string, and the beautiful little lantern is ready.
